Odopoea degiacomii Distant, 1912, was described by British entomologist W. L. Distant in 1812.

Odopoea degiacomii is a visually impressive cicada with a prominent pronotal collar that should inspire thoughts of Dracula the Vampire (like other members of the cicada tribe Zammarini). It won’t suck your blood, but it will suck xylem sap from trees.

Characters. — Head (including eyes) about equal in width t.. base of mesonotum, ocelli a little wider apart from eyes than from each other, eyes prominent, a little passing the anterior pronotal angles; face more or less longitudinally sulcate; rostrum about reaching the posterior cox*; pronotum shorter than mesonotum, the lateral margins angularly ampliate; mesonotum (including basal cruciform elevation) almost as long as head and pronotum together; abdomen broad, centrally ridged, the lateral areas more or less oblique, about as long as space between apex of head and base of cruciform elevation; operçula short, broad, not extending beyond base of abdomen; tympanal coverings outwardly complete, the orifices only exposed inwardly; tegmina three or more than three times as long as broad, apical areas eight; wings with six apical areas.

The illustration comes from the journal Genera Insectorum, and a specific article from 1914 by W. L. Distant titled Homoptera. Fam. Cicadidae, Subfam, Gaeaninae. Read it on the Biodiversity Heritage Library website.

Most of the information on this website is focused on cicadas of the U.S.A. and Canada. There are plenty of cicadas south of the U.S., of course. Recently we started getting identification (ID) requests for cicadas of Mexico, and with the help of experts (Geert Goemans and Allen Sanborn) and a paper from the early 20th century, I was able to ID them all.

A large number of the IDs were for cicadas with pronounced pronotal collars. Many of these look like the same species, but they’re not. Many of these species are found from Mexico, throughout Central America down to South America.

On this page are six collared cicadas that exist in Mexico, Central America and South America. Illustrations come from Insecta. Rhynchota. Hemiptera-Homoptera. Vol. I by W. L. Distant and The Rev Canon W. W. Fowler, F.L.S. I updated the names to their current names (the source is about 100 years behind the times, expectedly so). Note that the illustrations from this document are of dead specimens, so the colors were faded at the time they were illustrated.

Formerly Odopoea montezuma. This cicada is actually tourquois to pale blue when alive. Red eyes. No infuscation (coloration) in the wings. Link to original illustration..
